The things that you can change (depth of the network, the activation function, the learning rate, etc.) are called hyperparameters. So by clicking around in the playground, you are "modifying the hyperparameters of a feedforward multilayer neural network".

Building on our Primer on Artificial Intelligence, this microsite is intended to help newcomers (both non-technical and technical) begin exploring what's possible with AI... a resource for anyone asking those questions, complete with examples and sample code

The video distills the current state of AI into 3 waves... simplified presentation because it lumps all of machine learning, Bayesian methods and Deep Learning into a single category. There are many more approaches to AI that don’t fit within DARPA’s 3 waves. Pedro Domingos ... talks about the 5 Tribes of AI: Connectionists, Symbolists, Evolutiona…
